•
Preamps with Line Out jacks: connect one pair of Line
Out cables to your main amp to power your main L & R
speakers, and a second pair to the SW10II OR SW12
LINE LEVEL INPUT. If your preamp has only one pair of
Line Out jacks, you can use a pair of "Y" connector
cords, available through your NHT dealer.
•
Amps and receivers with Pre-Out jacks: connect the
SW10II OR SW12 from the Pre-Out into the SW10II OR
SW12's Line Input.
2) Hi-Level
Use if:
Your receiver has no Pre Out or Subwoofer/LFE Out
jacks
To connect for a High-Level signal (Fig. 4), use two addi-
tional pairs of speaker cables, and connect as follows:
•
For amps and receivers with separate A and B speak-
er outputs, connect one pair of speaker cables from your
receiver's Speaker A outputs to your main L & R speak-
ers, and a second pair from your receiver's Speaker B
outputs to the SW10II OR SW12's High-Level Input. Use
this method only if both A & B speaker outputs can oper-
ate simultaneously.
•
For amps and receivers with only one set of speaker
output terminals, simply feed the same signal, in parallel,
to both your main L & R speakers and the SW10II OR
SW12. Connect one pair of speaker cables from your
component's speaker output terminals to the L & R
speakers, and a second pair from the same output ter-
minals to the SW10II OR SW12's High-Level input. The
SW10II OR SW12's input does not present a significant
load to the receiver, and will not compromise its output to
the L & R speakers. If you find that your receiver will not
accommodate more than one cable per output terminal,
check with your NHT dealer for alternative methods of
connection.
With all signal connections complete, it is now time to
apply AC power. Plug the power chord into the power
inlet in the back of the subwoofer, plug the other end into
into the wall outlet and switch the subwoofers power to
the ON position.
